With all of the personal information it contains, Apple has added numerous security measures to your iPhone to protect you and your device from unwanted access. There are several changes in iOS 12 to make your device even more secure and private, and the update builds on previous improvements to make sure your data stays secure.
Even with these enhancements, the security of your iPhone still largely depends on you – from the security measures you use to the data you want to share with Apple and other parties. For this reason, we've rounded up the new privacy settings in iOS 12 that you should review, along with the settings that existed since previous versions of iOS.
Use Automated 2FA
Two-factor authentication, commonly known as 2FA, provides you with an additional level of security for apps and other services in the form of a six-digit numeric PIN that is sent to you through messages. In the past, you had to retrieve and enter a time-dependent code, which made access difficult. To avoid this, iOS 12 has made 2FA security codes available as AutoFill options .
In other words, you no longer have to switch from a sign-in page to messages to retrieve your security code, and then back to type it in. Unfortunately, the auto-fill feature does not extend to external 2FA apps like Google Authenticator and there is no specific information as to whether it will be added with future updates.
This is a security setting that you should keep in mind, considering how easy it is 2FA power. Once your iPhone has been upgraded to iOS 12, you should review all online accounts with sensitive information and enable 2FA, if available.
. 2 Monitor Your Passwords
To further enhance your privacy and security, iOS 12 introduced Password Reuse Auditing, a feature that tracks stored passwords and identifies identifiers for different accounts. This can be achieved under Settings -> Password & Accounts -> Website & App Passwords. From there, accounts with identical passwords are marked with a triangle with an exclamation mark.
Tap one of the suspicious accounts and select "Change password on website" on the following page to create a new password. 19659012] 3. Restricting USB Restricted Mode
Brute-force USB unlocking tools such as Cellebrite and GrayShift have become popular in law enforcement circles nationwide as they can circumvent iOS restrictions on the number of incorrect passcode attempts , This allows officers to unlock seized devices by entering an unlimited number of guesses until they finally exit the lock screen.
To combat this, iOS 12 has USB Restricted Mode, which requires you to unlock your iPhone. Password when connecting to a USB device. Unlike previous iOS betas, which required only a password for devices that were not unlocked for seven days, iOS 12 (and iOS 11.4.1 earlier) reduced the request window to one hour.
This stringent requirement effectively nullifies the ability of law enforcement agencies to unlock suspicious iPhones with USB unlocking tools, since they only have a 60-minute window to gain access to the device before the password request entry. However, if you want to disable this feature, go to Settings -> tap ID and Password, and tap the button next to "USB Accessories" to turn it green.
4. Disable Face ID (iPhone X)
With the upcoming first anniversary, it's safe to say that Face ID has proven to be a reliable way to unlock the iPhone X while protecting against unwanted access. Nothing is bulletproof though. Apple advertises a false acceptance rate of 1 to a million for Face ID, and considering that there are 7.6 billion people on Earth, about 7,600 other people can unlock your iPhone.
If that's not enough, there's an even greater likelihood that someone will use your own face violently against your will to gain access to your iPhone. So if you want to maximize security, we recommend disabling the Face ID altogether by going to Settings -> Face ID & Passcode. Instead, use a strong password, slightly longer than a six-digit numeric password.
. 5 Temporarily disable face ID (iPhone X only)
If you need to enable face ID, do not worry. Apple has introduced a quick way to temporarily disable Face ID, if you know your physical security is compromised. Check out our guide below to find out more about this option, which leaves the security of your phone in the hands of your passcode.
Just like the iPhone X with the Face ID, the Touch ID can be a problem on other iPhone models. For one, you do not want to store your fingerprint in a database, even if it's located on your iPhone locally, because someone might be able to retrieve that record with access to your device. In the long run, it is much safer to use a less convenient code. You can deactivate the Touch ID using the Touch ID and Passcode settings.
As with Face ID, you can temporarily deactivate the Touch ID if you do not want to permanently lose the comfort of the Touch ID. With a specific key combination you can disable them before you hand them over to law enforcement, thieves or even curious friends and family members.
The iPhone passcode is six digits by default, but you can still set it to four digits. While there is nothing fundamentally wrong about using these passcode restrictions, they are not the safest. For example, a four-digit passcode has 10,000 possible combinations, and considering that in the United States alone, 85.8 million iPhone users are there are simply not enough unique combinations to get around.
Increasing the passcode to six-digit numbers increases the number of possible combinations to one million and matches the odds of Face ID. If you want to go beyond these benefits and maximize the security of your iPhone, change your passcode to a password because using a real password with a combination of letters, numbers, and special characters makes your lock screen virtually impenetrable
It is true It's not ideal to enter a wrong password into the phone if you want to use it, but it's currently the safest way to lock your iPhone. So if you want a balance between comfort and security, choose a six-digit code with four-digit code, avoiding common passwords like 123456 or six of the same number.
To change your iPhone's password, go to Settings -> Touch ID & Password -> Change Password. Enter your old passcode when prompted and tap Passcode Options to select the type of passcode you wish to enter.
. 9 Do not show parked location
If you connect your iPhone to your vehicle via either Bluetooth or CarPlay, your iPhone can record the location of your parking location. While this information may be useful to others, it may feel like a complete violation of privacy. So if you feel like the latter, you want to turn that feature off, of course. To do this, open your app settings and tap on "Maps". Then tap the switch next to "Show Parked Locations" to turn it off.
10. Disabling and Deleting Important Locations
"Significant Locations" is a setting that allows Apple to record a list of your most visited locations. And while this may optimize some apps based on location services, privacy improvements may outweigh the improvements overall.
So, if you do not like to tell Apple about places you visit frequently, go to Settings -> Privacy -> Location Services -> System Services -> Significant Sites, then turn them off. From there you also have the added option of erasing the history that your iPhone could have accumulated over time.
. 11 Disable Location Alerts, Apple Ads, and Proposals
When this option is enabled, location-based alerts, Apple Ads, and Proposals will track all locations to provide targeted alerts, announcements, and options. To say that these options are not the most privacy-protected features in iOS 12 would be an understatement. In fact, these settings are actually scary.
So if you do not want to be targeted by Apple, open your Settings app, select "Privacy" and tap "System Services" on the following page. From there, you can turn off Location Based Alerts, Apple Location Finds, and Location-Based Suggestions by disabling their respective switches.
12. Disable Sharing My Location
If My Site Sharing is enabled, you can send your current location to a friend who requests it. While you must agree to this agreement with another person using the Find My Friends app, there are ways to track your iPhone without your permission. To completely avoid this risk, disable the option by going to Settings -> Privacy -> Location Services -> Share Location.
Alternatively, you can change the device that shares your location if you have more than one attached to your Apple ID. You can also contact friends of yours who have approved you to see your location.
